Abstract

1486115 Pt-Ni-Co magnetic alloy SONY CORP 6 Feb 1975 [13 Feb 1974] 5163/75 Heading C7A A magnetic alloy consisting of platinum, nickel and cobalt in atomic proportions Pt x (Niy Co 1-y ) 1-x where x is not less than 0À45 and not more than 0À55 and y is not less than 0À65 and not more than 0À86. The alloy may be used as an intermediate carrier in thermal and magnetic printing of video signals in which processes it is heated to 130‹C or 210‹C.
